                The
                series of LN850-40
                is a GaAlAs LED mounted on a metal stem and covered with
                epoxy resin
                or hermetically sealed with Φ5
                glass-lens can.
                On
                forward bias, it emits a high power radiation which peaks at
                850nm.
